英文:
what's the mearning of `sudog` in the channel struct in Go?
问题
根据Golang源代码：
sudog是一个等待元素的goroutine。sudog结构体具有以下元素：
type sudog struct{
g *g
isSelect bool
next *sudog
prev *sudog
elem unsafe.Pointer //数据元素
...
}
我想知道sudog的隐藏含义是什么？它是什么的缩写？
英文:
According to Golang source code:
A sudog is simply a goroutine that is waiting on an element. The sudog struct has these elements
type sudog struct{
g *g
isSelect bool
next *sudog
prev *sudog
elem unsafe.Pointer //data element
...
}

普遍的共识是sudog是一个伪G，因为它用于维护G的列表。关于这个问题在https://golang.org/cl/20774上有一些讨论。
英文:
The general consensus is that a sudog is a pseudo-G, as it is used to keep a list of G's. There is some discussion on https://golang.org/cl/20774.
